Kudos (IPA: /'kju:dɒs/, from the Greek κύδος kydos, literally "that which is heard of") means fame and renown resulting from an act or achievement; by extension is often used as a praising remark. It entered English as British university slang in the early 1800s. Frequently used by Time magazine, it came to America in the 1920s and 1930s.

Note also that the word is singular, not plural. Thus one can say "much kudos" but never "many kudos".
